[PATCH 7/8] arm64: dts: imx8dxl/qm/qxp: Move power supply properties to Root Port node

From: Sherry Sun <hidden>
Date: 2026-03-25 11:02:24
Also in: imx, linux-arm-kernel, linux-pci, lkml
Subsystem: arm/freescale imx / mxc arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

Move the vpcie-supply and vpcie3v3aux-supply properties from the PCIe
controller nodes to the Root Port child nodes to support the new PCI
pwrctrl framework.
